c# - MemberExpression actual values -

class sometype {     public string value { get; set; } } 

lets have create function call below notation:

var someinstance = new sometype(); dosomethingonexpression(()=>someinstance.value); 

where method should that

void dosomethingonexpression<t>(expression<func<t>> exp) {     memberexpression mexp = (memberexpression)exp.body;      sometype sometypeinsance = ... //from mexp (1)     string sometypevaluestring = ... //from mexp (2)     string someintancemembername = (memberexpression)exp.body).member.name;       assert.equals(sometypeinstance.value, sometypevaluestring) } 

any idea how accomplish this?

so basically, question is: can extract member value memberexpression (2) , if can extract instance of type owner of instance
